When you go into an auto dealership, you’ll never hear a car salesman say ‘NO!’ when you pick out the car you want to buy. If you want one of their cars, and you have the financial wherewithal to make the purchase, they’ll get the paperwork ready in a hurry before you change your mind. But purchasing a solar energy system for your home is not the same thing. There are times when the installer should say, ‘NO!’
Why do you want an installer who will tell you ‘No!’ The answer is simple; you want to work with a solar energy system company that is focused on providing its clients with properly installed and cost-effective equipment.
There are times when a home just isn’t right for a solar energy system, at least, not on the roof. And there are reasons this may be the case, including:
- Orientation of the Home: A home can use a solar energy system on its roof if that home has a roof with usable space facing from 90-degrees (due East) to 270-degrees (due West). Here in Northern Illinois and Southern Wisconsin, as with the rest of the United States, we are in the Northern Hemisphere. Even at the height of summer, the sun is still oriented more to the South. Putting solar panels on a roof facing North is a waste of time and money.
- Workable space on the Roof: If there are ridges, gables and/or dormers on a roof that break up free area where solar panels can be installed, this can represent a problem for installing a solar energy system. Additionally, different ordinances in different areas call for specific setbacks. For instance, you may be required to allow from three feet to 18 inches from the edge of the roof or peak to the solar panels. This is to allow room for firemen to walk if there is a fire. The setback reduces the workable space available for solar panels. Generally, you want a flat, workable area for at least 10 solar panels.
- Condition of the Roof: It doesn’t make sense to install solar panels on a roof that will require replacement within a few years. The solar panels have to come up to replace the shingles. A responsible solar energy system installer will definitely say, ‘No!’ if the roofing is too old.
- Trees and Obstructions: If there are trees or other obstructions that block the rays of the sun, they also block the effectiveness of the solar energy system. A system needs to be reasonably efficient for it to be practical.
Of course, if these factors require an installer to say ‘No!’ when you want to put solar panels on your roof, it’s possible they could mount the panels on the ground, if there is an unobstructed area to do so. But, otherwise, a reasonable solar energy system installer will say ‘No!’
An installer responsible enough to say ‘No!’ when the conditions merit such an answer is also a solar energy system installer who will do a quality job.
